btw had to order a replacement screen from hong kong..not available in u.s yet

cant be done. Must buy the lcd + digitizer together. I tried separating the digitizer from screen and ended breaking the lcd. It just showed up black and nothing else.

I've done it myself after I lost my Arc on the pavement. It's not that hard really. It took me an hour or so to complete the exchange. The hardest part is splitting the screen and backframe (or what it's called) from each other. There are lots of clipses holding this beast together.
But it can be done

Lol an hour sounds time consuming...on a side note tho the design of it seems flawed. my friend sat on it with the phone in the back pocket. i do this with all my phones and never had a screen issues...i think the curved back may have bent the screen more than my friends fat a$$

UPDATE: finally got the screen from hong kong for 66$, it was easy to take apart, actually 1 of the easiest ive taken apart so far. the motherboard chip set separates easily from the front housing holding the lcd and digitizer, theres also a guide available on how to disassemble it on xda. thinking about getting my own arc now...hmmm

Hi, my arc s fell from motor cycle yesterday, the screen smashed pretty bad on bottompart. It still boot normally, what part do you guys think nee to be replaced? Thanks before.

[Q] How do i know if ribboncable or digitizer is broken?

My touchscreen on the htc desire Z has stopped working, but buttons, trackpad and screen works. Is there any way to find out wich part is broken?
I´ve taken it apart and the ribboncable LOOKS Ok, but i dont know.
The screen has som marks on it.
When the problem startet, it stopped working sometimes when i had the keyboard out, so my guess its the ribboncable

any help?
Is there anyway to check this on my own?

trial and error? i have a spare (and am having a similar issue) im about to replace my ribbon with the one i know is good, if this dosent work ill get a new digitizer. of course my experience wont necessarily be the same for you. but ill say i bought a g2 off ebay that only the bottom half of the digitizer worked, zero from the middle of the screen up. all the soft buttons were fine and there was no marks on the screen. a new digitizer fixed that.

I had to buy a ribboncable from ebay but the shippingcost is 39usd... Thats why i don´t want to buy both the digitizer and ribbon because i cant fint anyone who has both :/
but i hope its the ribboncable, it has to be when the screen stopped working when i used the keyboard, and worked again when i closed it. right?

Hello again, i changed the ribboncable, and it all worked
BUT.
I had to open it again because the flash stopped working, and the second time i opened it, i broke these ribboncables for the keyboard.

I change to jokawild v3, and no flickering happens, the best i current used, search the development thread for more information.

I'm using CM9 RC2 with included kernel and everything seems to be working just fine, remember to wipe data, cache and dalvic cache before flashing a custom rom.

Sounds like a problem with the flex cable, people have had this happen to them and the fact that sliding it out only makes it more feasible that it is the flex cable.
EDIT- Here's a whole thread of people discussing the problem you're having http://forum.xda-developers.com/showthread.php?t=1527498&highlight=flex

I've fix a lot of Xperia Plays and I can assure you that the problem is caused by a faulty flex cable. With the sliding mechanism, eventually the flex cable gets worn out and the signal for the screen gets garbled exactly like in that picture. The damage comes in varying degree so even if you see the screen sometimes it still means you have a problem with your flex cable. You can buy the individual flex cable cheaply on eBay but if you don't want to take your phone COMPLETELY apart (which is necessary to switch out the flex cable since it is behind the LCD), you can buy the front housing for a higher price which is MUCH easier to switch out since you only need to take off the backing, pop of the cable connector, separate the lower housing from the upper housing and switch in the new upper housing.
There's a very thorough picture guide somewhere in the forum for fixing any part of the Xperia Play.

Thank you guys! Just bought a complete replacement to my PLAY : Front. Back, touchpad. gamepad buttons all of that
Haha you can see that my PLAY looks a bit busted

As you can see there, half my screen has gone grey. Basically, here is what I know about it.
It's a hardware problem, not a software, because I have restored and flashed multiple ROMs since it happened
If it's the flex cable, it's not the usual issue because sliding the phone open does not help at all
It's not stuck pixels, because they usually don't show up in a pattern like that. And shaking my phone a bit can sometimes make me lose one row of pixels to the grey bars, or gain it back
If I figure any more out about it, I'll post it. But my main question is, what is the problem, and how can I fix it?

Bumpin'

obviously the screen is broke lol so the fix would be replace the screen

What tools am I going to need to do so? I'm going to replace the digitizer as well since it's shattered. (That happened in a separate incident)

Well, i dont really know, but beware, you'll need to unstick LCD from digitalizer (cuz its one piece, but 2in1).. But in most times when unsticking the dig from LCD, you can broke the dig too..

The digitizer and the LCD re two different parts of the phone and they are not sticked together. And, this is a flex cable issue. I've got two Plays here in front of me with almost the same issues. I just can't buy a new flex cable here in my country, 'cause all of them is sold out..

Actually, this isn't a flex cable problem. I know what that looks like, and it's not this. It also doesn't have any of the same symptoms.

Problems after screen replacement.

Hi guys,
Two weeks ago, I had broken my screen. I bought used screen and I go to the mobile service to replece broken screen. It's works two hours, after this time I started have problems with screen. When I wake up phone, it's works OK by 10-15 sec, after that time, on screen apears white or coloured stripes . Here is the photo which shows problem:

Anyone have same problem or have any idea how I can solve it?

Hi,
I think it definitely bad connection between screen and motherboard:
badly installed (I mean someone who installed touched touchscreen connecting pins with fingers) ... or ... oxide on touchscreen connecting pins ... or ... possible water damaged used screen (seen one analog case).

It's any possibility to repair connection if screen it's OK?

Anyone know smoething about two types screens in G3?
It's similiar to that problem :https://www.youtube.com/watch?v=DI64Bcf8OiE
which it's solved by: http://forum.xda-developers.com/showpost.php?p=52414185&postcount=122
Maybe changing kernel/soft will solve problem?

Hi,
Actually about software side I dont believe. I hope this used one was exactly same, what you had before. If I remember right, then LG didnt made different screens for G3 different models.
I remember that G2 had many problems with white lines after drop or screen change. Fix was easy, to add metal tape at display connector to antenna. To understand better about what ia talk you must read this link.
Anyway, I sill think your problem is hardware problem if on start it works normally.

In g3 it's any chance to solve that with metal tape? In g3 motherboard it's different so maybe tape can't help. Tomorrow I'll try one more time check lcd plug.
